For anyone that's curious, This is what I remember: The story had a theme of extreme paranoia, more specifically the main character being spied on through the outlets and electrical wiring in his home somehow. I believe he had pretty much barricaded himself in his home. Another character, an asian woman I think, possibly the main character's girlfriend, commits suicide (or is driven to it by whoever's spying on him) by rigging the door to a microwave and sticking her head in it. I know it was published during the years I posted above, because I had a subscription to those years.
